Barailon, Jean-François (1743-1816).

Jean-François Barailon obtained a doctorate in medicine at the University of Montpellier, served as a delegate to the Convention nationale and subsequently to the Conseil des cinq-cents for the departement of La Creuse, and was a member of the section of medicine and surgery at the Institut de France. He participated in the coup d'état of 1799 which brought Napoleon to power as the First Consul of France.

Guillaume François Rouelle, a chemist of high reputation and broad influence, was a chemistry instructor at the Jardin du Roi. His chemistry courses had a large audience which included all the important chemists of the day, Antoine Lavoisier among them. Lavoisier was influenced by Rouelle's research methods. Because Rouelle never published his work, his students' notes from his lectures, which were rapidly circulated at the time, are the only remaining record of his thinking. About 10 different manuscripts of these student lecture notes are known to survive.
